3, Claims. (01. 220 s3) j'Ihis invention relates to the 'field of display boxes, display bases, caskets and the like, suitable for displaying, setting off, holding or encasing articles of jewelry, watches, and other small objects Boxes in which the outside of the receptacle part gives the appearance of a broad rim or massive section and is extended beyond the contour of the cover, have been made of wood, cardboard, or sheet metal, covered or uncovered. A known form of sheet metal consctruction for such boxes is one involving a frame with internal,

flanges, the manufacture of which requires that the external configuration must be produced at the initial metal working operation, in consequence of which each style of frame of the same size must start with a different first-stage prod: not. The flexibility of such frames is such that; in'practice, they are made rigid by an additional metalplate, riveted or clinched to the flanges. The frame typeof construction was devised for box receptacles in which'the metal was covered with flexible material after the first forming .op-'

eration. The present inventionis also applicable to receptacles the metal of which is covered by fabric, and is especially adapted for the manufacture of receptacles a beauty of which is in exposed metal, plated, brushed or polished to an attractive finish.

An object of this invention is to provide a decorative receptacle construction of sheet metal, which is of one piece, inherently rigid and relatively light. Another object is to provide a lowcost construction, advantageous for quantity production, and which can be made in a wide variety of configurations from the same initial product or with use of the same dies in the forming of the initial product, no matter what the configuration of the final product may be.

In the accompanying drawings, forming part hereof:

Fig. l is a perspective view of a piece of sheet metal from which to form one of the receptacles of the invention;

Fig. 2 is a perspective View of the product of the blanking and drawing step;

Fig. 3 shows the result of the next step, which is the piercing of one of. the boundary walls and forming hinge-attaching lugs;

'7 to 10 are fragmentary sections showing other configurations of the outer shell of the 5 receptacle. 7

In the manufacture of a shallow box receptacle in accordance with this invention, a piece of sheet metal i2 is operated upon by dies in a blanking and drawing operation so as to produce the partly 10 formed blank 53 of Fig. 2. This blank has a bottom wall M offset from the plane of the original sheet, four low cavity-bounding walls l5, and a broad flange it projecting horizontally outward from the tops of the bounding walls. .All of these portions are continuous with each other. The first-stage product is made in the same way'as a simple box body, and is like the ordinary metal box-body before it is trimmed, with the important differencethat, instead of .there'being only a slight amount of excess metal to cut away, the broad flange is provided this flange containing the metal from which the hollow exterior of theire'ceptacle of this invention is later formed. The first sta'ge product is of such strength that it canibe stored without care in large quantities and handled in any manner without suffering injury.

The next step is the piercing of one of the bounding walls with bending in of the hingefastening lugs l8.

Next the blank is drawn between dies which form and shape the integral shell H! which surrounds and conceals the walls I 5 and gives horizontal extension and apparent thickness. The encompassing shell of Figs. 4-6 is one having a horizontal top 28 continues with the walls l5 and a vertical down-turned skirt 2| extending to or below the plane of the bottom. In conjunction with the cover 22, when closed, the effect produced is that of a one-step plinth or extension beyond the lines of the cover.

Figs. 7 to 10 show certain other of the numerous outer configurations that can be produced with appropriate dies from a'first-stage product such as shown in Fig. 2. The two-step formation 5 of Fig. 7 comprises a horizontal top portion 24,

a vertical portion 25 extending downward therefrom, another outward extending horizontal portion 26 at an intermediate level, and a final vertical portion 21. All such portions are continuous with each other and with the walls [5 around the entire circuit of the receptacle. The threestep construction of Fig. 8 comprises top portion 28, vertical portions 29, 3| and 33 and intermediate outwardly extending horizontal portions 30 and32. Fig. 9 shows a beveled extension work,

consisting of a sloping portion 34 and a verticallower portion35. Fig. 10 illustrates a molding efiect, having top portion 36, upper vertical portion 31, curved portion 38, lower horizontal portion 39 and. a vertical portion 40 at the bottom.

In any case there is a fin 4|, of excess metal, as shown in Rig. .4, extending outward Irom the bottom edge ofthe external shell, .it being necessary to provide for this fin by the size of the original piece of metal or by thedepth of the first draw, in order to insure the production of 'a complete and perfect exterior for receptacle A further step is, therefore, the trimming off of V the fin.

-thelbottom .plate or wall l4,.and an outer label 4] of cardboard, paper or other material, is .applied under the bottom to form abottom coverl ing and to provide the surface which contacts with a table-top or other underlying surface. This bottom label may be held by causing the edgesol theholes 44 to penetrate it and upset ting .these edges. A neck 48 is set within the bounding walls 15, and may be held by bending the lugs 43 against it. A pad-of any suitable kind is inserted into :the vreceptacle, within the neck 'to support the watch or other article-which the' box is .tohold. A pad is indicated by the broken lines :50. p

, The cover v.22 maybe made,.co.vered, lined, and hinged inzcustomarymanner.
